Example - Occupancy analysis for a hospital short stay
unit

Patients flow
through a Short Stay Unit for a variety of procedures, tests or therapies. Let's
assume patients can be classified into one of five categories of patient types:
ART (arterialgram), CAT (post cardiac-cath), MYE (myelogram), IVT (IV therapy),
and OTH (other). From one of our hospital information systems we were able to
get raw data about the entry and exit times of each patient. A portion of the
input data table is shown in Figure 1. We'd like to create a
graph that shows the total average and 95th percentile of occupancy
and the number of arrivals by time of day and day of week. Hillmaker is
designed for precisely this problem. In Figure 2 you can see
the Hillmaker main form. Figure 3 shows part of the summary
output table from Hillmaker that will allow us to create such a graph. You can't
see them in the screen shot, but the 50th, 55th, ..., 95th percentiles are
included as fields off to the right in the table. Figure 4
shows the occupancy graph for Monday that was created the Excel based grapher
that comes as a part of Hillmaker.
